Can't Mount SD Card

Hey Everyone,
I apologise if this is in the wrong forum (not sure if it should be in Android Development), and before I start I want to make it clear that I DID use the search function, I searched for "Can't Enable USB Mass Storage" and "No option to mount SD Card" with no relevant results.
Rom: JFv1.51 CRB43-EU
Ok, I was using my phone fine I managed to sync around 12GB worth of music and transfer a few files last night (I flashed the ROM around 20:00 GMT after trying out several hero builds).
This morning I mounted the SD Card to my laptop (OS is Windows 7 RC1) and transferred a few APK's. Suddenly as I was in the market the phone comes up with "Checking SD Card for Errors" and had for some reason unmounted itself from the PC.
Now when I plug in the USB cable all I get is the light to indicate it's charging. There's no option to mount the SD Card. I've tried it on my Laptop, My Vista Desktop AND My Xbox 360 (usually there's a mount option when you connect to that which allows the xbox to see music on the phone).
Strangest thing is the MicroSD Card seems fine, I am able to play my music and see the 2 pictures I have stored on it. Another site suggested using Anycut to make a shortcut to SD CArd and then ticking Enable USB Mass Storage. This doesn't work either, I get a ! in a triangle in the status bar saying USB Mass Storage Enabled but neither my laptop or my desktop will pick it up.
Any Suggestions?
Thanks,
Steve.

Yep, Should it be?

Yes it should be. Try uninstalling and reinstalling the drivers (USB mass storage devices)

idk if u mean u cant connect through adb, or jut read ur SD card.
with adb, reinstall the most recent SDK, make sure all paths are set
with SD, try it with just a regular card reader and see if it works. then move on from there
if u need more details, post more details. just not rlly sure where the problem lies yet.

i cant read my sd card, it works in every card reader it works in other peoples g1, it works in other peoples mt3g, but in my g1 when i connect it to computer i dont get the notification of "usb connected mount/dismount" so i cant even mount my sd card so i can drag and drop files on it via computer (usb mass storage) it charges when its connected to pc just no notification so now i have to carry my old g1 so i can put m sd carrd in there and connect to computer and use it as a card reader

i have literaly tried everything(i think)

suddenly applications on sd does not work

i did nothing new, no update, just while installing some games, pc suite got a freeze, i restarted my pc and my DHD, all applications installed on the sd card are not working, but my sd card is mounted and i can access sd card root using astro, also i tried to install some apps using astro, but installation bar progress takes forever and didnt finish, even installing from market did not start.
any suggestion on what is going here?
P.S.: i tried to unmount than mount my sdcard, and nothing changed.

this is turning very serious, plz i need help.
i did a factory reset, and i did install the stock rom from sdcard, both ways keep the problem, that i cant sync the device or mak it appear as disk drive, i can only make a internet passthrough connection, but no drive no htc sync, i did a lot of tries, debug on off, connect reconnect usb, restart device, restart pc, use another pc, i also have stock rom .6, and original kernel with latest htc sync installed.

m very frustrated now, i have no recovery, the device wont accept installing anything from pc, or from market place, installing process takes forever and do nothing, the problem is in the device not the pc, is there a way to get back my device to operate properly, please help

Is you SD card corrupted? Can you access it?

i will list it again as following:
-stock rom .6 with original kernel
-radio s off
-no recovery
-sd doesnt seems corrupted cause i can access it once with astro, and i can access it with pc suite only as disk drive
-i tried with mounted and unmounted sd card (no fix)
-i did a factory reset (no fix)
-i did install the rom from sdcard (no fix)
-i tried another pc for syncing (no fix)
-i can only make internet passthrough but no disk drive or htc sync
-in market i can press on install but nothing will happen
-in desktop htc sync, if i get luck and see it, if i browse to install an apk, it will simply freeze.
please all i need urgent help, i think something bad happened to my device

How about copying all the data from yr sd card into another card? Your current card could be faulty but stil accessible by astro.
You could also try copying everything out to your PC and then reformat the card and copying everything back.
If stil don't work then start brand new by reformatting the card and reinstalling all your apps

i will try it man for sure but just for informations:
-say i have no sdcard in the device (sdcard is unmounted) should i be able to install from market or install from pc some apk?
if yes than the problem is not in the sdcard, if no than i have hope to do it.
P.S.: how can i format the sdcard if i cant access it as disk drive?

You can format from within Android, Settings -> SD Card & Phone Storage -> Unmount first then Format.
Have you got another SD card to try with?

-i formatted the sd card, insert it in DHD (doesnt work)
-i replaced the sd card by another one (doesnt work)
-reinsert the new sd card and reboot (now problem is fixed)
-now back to the original sd card (and yes the problem is fixed)
what happened i dont know, why it's fixed i dont know, it's like a sudden problem and sudden fix, if anyone have any idea of what happened plz enlight us for future or similar issues.

[Q] Does mounting the sdcard as diskdrive really screws up a2sd?

I've read somewhere here in the forums that it can screw up the a2sd function
so how can i connect the phone to my PC (because using a card reader every time you need to connect your phone to a PC is @[email protected])
Is this true? any alternative?
I'm using wildpuzzle ROM btw

Hi Dudin.
As standard, when you connect the phone to the pc as a removable storage, Android prevents the SD from being seen by the phone at the same time. As A2SD installs apps to the SD, this obviously causes any Apps on the SD to not work. I dont think its a permanent screw up, as it all should right itself after you disconnect from the computer, but you do have options:
1:Connect as Sync or Charge only. (a quick but pointless workaround if you want to browse your Sd card from the pc),
2: Or do as I do and install "Dual Mount SD" from the market It makes the SD card accessible by both Android and the USB at the same time. Works perfect for me, I can still use my aps and access the SD from the PC simultaneously. (I have used it on Wildpuzzle, Openfire and Cyanogen Mod, Eclair and Froyo versions). You need to be rooted for this though as it asks for superuser permissions.
Hope this helps.

Ok I will clarify for you. If you use dt app2ext patch. When you mount your sd card, the computer mounts the fat32 partition, and does not detect the ext partition, so it does not screw your card up, or the apps.
if you are using froyo app2sd, the apps that are on your sd card will not work when the sd card is mounted.

thanks for the replies

I find a good alternative is Dropbox - and it is mentioned in a lot of threads.
I already used it for work and it is great. No looking around for a USB cable or turning off/remove case/remove card etc which takes ages! Dropbox is free so give it a go! I use it in conjunction with EZ File manager (i think thats what its called) to transfer stuff and unzip archives.
Hope it helps!

[Q] Unable to connect USB or to unmount SD Card

Since a few days I try to connect my phone on my computer but each time I push the button "activate USB mass storage memory" my telephone reboots. I have the same result when I try to unmount my SD Card from: Options>Storage>Desactivate SD Card.
I tried to Format my Sd Card, to re partition it with Rom manager but it's always the same.
May-be a track: After formating my SD, if i try to connect my phone, every thing is fine. I imagine it comes from the folder ".android_secure" because when it's empty I can access my card but when it's full of my apps I can't, it reboots. Inside of it I have about 60 files for more or less 200Mo.
I even tried with another SD-Card and the result is the same.
May be something that could help: when I connect my phone the debug icon turns green.
Thank you by advance for any help you could give me.

Well, I tried something new after reading several posts in many differents forum.
First of all I tried to de select "USB debug" in "aplication>developpement" and I could connect my phone and see the content of my SD Card. My telephone didn't reboot.
Now, I've found an application called "Multi Mount SD-Card" that keeps me going in the menu Developpement each time to select or deselect "USB Debug". It works fine but I imagine it should'nt be like this.
Whatever, I've got the result I was expecting.
